If lucky enough, alsamixer will let you either mute or lower the volume of the PC speaker. This is an easy way enough to get rid of the beep.

Else, you can get rid of the kernel module which is responsible of making the PC speaker beep.

pcspkr, this is the guy we are looking for here. So let's get rid of it!

$ sudo rmmod pcspkr

And that's it!! Go back to you virtual console (Ctrl-Alt-F1), tab around.... no sound :D.

Cool, but now, it would be quite handy to get this done on each reboot. To do so, we need to blacklist pcspkr module.
